# Fee Builder
Depending on the network and DEX you launch on, this system may be referred to as **v4, Infinity, Burn & Earn, or Lock & Earn**. On basedbid, it all runs through the same underlying architecture described below
Fee Architecture
* **LP Fees** are standard fees earned from your liquidity position. When collected, you receive **50% in native token** and **50% in project token**
* **Fee Builder** is basebid's custom hook, sitting on top of LP fees and capturing a programmable fee directly at the swap. **No token sells. No thresholds. No red candles****.** You choose where it goes: **holder rewards, buybacks, liquidity, or any custom wallet** (marketing, KOLs, team, partners). No limits
Add Fees to Your PoolAdd Fees to Your Flash Token
Fully Modular
You can add, remove, or reconfigure fee destinations anytime after launch, no redeployment needed. Start with rewards, add buybacks later, swap out a wallet. **Your token evolves without relaunching**

Built-In Optional Protections
* **Tiered Fees:**
* **Dynamic Fees:** **Auto-adjust** based on volatility
* **Anti-snipe/Anti-MEV:** **Bot protection** at the pool level
* **Cooldowns:** **Enforced gaps between transactions** with penalty fees

Example
**Example: $VAULT**
$VAULT launches on basebid with **2% LP fees** and the **Fee Builder enabled at 5%**, configured as follows:
* 2% to **holder rewards**
* 1% to **automatic buybacks**
* 1% to **liquidity**
* 1% to a **marketing wallet**
On a day with **$100,000 in trading volume**, $VAULT generates **$5,000 in hook fees**. $2,000 goes to holders, $1,000 buys back tokens automatically, $1,000 deepens liquidity, $1,000 goes to marketing and $2,000 goes to the creator. in **All from swaps, nothing sold**
$VAULT also launches with all pool protections active:
* **Dynamic fees** set to Medium (2x multiplier), triggered per swap, with a 10 minute decay period
* **Snipe protection** active for the first 10 minutes post-launch, capping any single buy at 0.1% of supply
* **Cooldown protection** enforcing a 10 second gap between buys, with a 1% penalty fee for wallets that try to bypass it
* **MEV protection** enabled, blocking front-running and sandwich attacks
Three months after launch, the team decides to remove the marketing wallet and redirect that 1% to increase **holder rewards** to 3%. **No relaunch. No migration. One config change** and the token is running a new strategy the same day. On that same $100,000 volume day, holders now earn **$3,000 instead of $2,000**
